VUNITED STATES PATENT FFIUE.

CHAS. H. BEATTY, OF VHEELING, VIRGINIA.

DOOR-LOCK.

Specification of Letters Patent No. 8,426, dated October 14, 1851.

To all whom it may concern Be it known that I, CHARLES H. `BEATTY, of the city of Wheeling, in the State of Virginia, have invented certain new and useful Improvements in Locks; and I do hereby declare that the same are described and represented in the following specification and ac companying drawing.

The nature of my invention consists in the combination in the same lock of the bolts D, D, provided with two sets of diagonal slots g, g, or their equivalent, the slide E, running at right angles thereto provided with two pins f, f, which work in the diagonal slots g, g, in the bolts D, D. The two key notches L, L, in the slide E, and the two drops I, I, which are placed on the two pins (l, d, and working or turning on the latterthe tumbler' F, is placed on the opposite side of the key and hole from the slide E, and the several parts are so constructed, as that the lock may be placed upon the door with either edge uppermost. Vhen the key is used the operator is compelled to throw out the bolts by shoving the slide down, and to draw them in by shoving it up, it being immaterial which edge of the lock is upper most.

The slide E, and drops I, I, perform different offices as is apparent from an investigation of the drawings. y

The advantage of the slide is that two or more bolts can be thrown out by a single half turn of the key which is an importantconsideration where strength is required, the several bolts' being independent of and unconnected with each other.

The advantage of the drops I, I, is that they force to operate to move the slide E, down in order to throw the bolts out, and then the operator is certain that the bolts are thrown out and remain out and that no second turn of the key has thrown them back as might be the case where the key is turned entirely around, with the drop in and when a half turn of the key is made the bolts are thrown out and the drop prevents the key from being turned further in the same direction.

In the drawing the slide E is so placed as to require the operator to turn the key to the reverse of what is usual to lock or unlock-that objection is answered in larger locks by puttingV the slide E, on the opposite side of the key hole from that in which it is placed in the drawing. By which the direction of the key to lock or unlock is reversed and the operator locks or unlocks by turning the key in the usual way.

The bolts D, D, the slide E and the drops I, I, are all held in their position by the two pins CZ, d, and although it is composed of several different parts necessary to throw two or more bolts out by a single application yet it is free from complexity, and is in truth so simple that there is scarcely a possibility of its getting out of order.

To enable others skilled in the art to make and use my invention I will proceed to describe its construction and operation.

Figure 1, the front of the case; Fig. 2, the back, with the several parts in their respective positions, with the bolts shoved out, ready to receive the back plate; Fig. 3, the front end of which is made to catch under the notches c, a, of the case; the back end is secured by the screw cz,through the screw hole a2, (the same letters refer to the same parts in each of the gures), Fig. 4, H is the catch pressed forward by the spring G, Fig. 5, and drawn back by the T lever, Fig. 6, the stem of which passes through the hole in the spindle B, Fig. 7, and fastens it into the lock, and the arms act upon the projections o, b, of the latch, to draw it in as the spindle is turned by the knob B, when the knob is released the spring G upon the pin n forces the latch forward the long end, acting against the projection b, Fig. 8 D, D, bolts, the front ends slide in the openings in the case and the slats C C, in the back ends t-urn upon the pins Z (Z in the face plate. The slide E, Fig. 9, is operated by the key 7c, Fig. 10, in the hole s, which acts against the point C to lock,'and against the shoulders C C to unlock; as the slide is moved down the pins f f, which are attached to it work in the diagonal slats g g of the bolts D D. Vhen the slide E is raised the pins f f draw in the bolts. The slats g g extend diagonally each way so as to shove out the bolts by forcing the slide down.

Let the lock be placed upon a door, either edge up, as the drops II, Fig. 11, which hang upon the pins el, CZ, the upper one always hangs down and overthe cleat n upon the slide E, and prevents it from being raised by the key, and compels the operator to shove out the bolts by forcing the slide down; while the lower drop falls over and lays upon one leg of the latch H.

The slots z' i in the slide E traverse upon the pins Z el. The tumbler F, Fig. 12, vibrates upon the pin 7c in the case, and is pressed into the notches 7 7 7 in the Slide E by the short end of the spring G, which acts against the swell m. As the key is turned, one wing raises the tumbler F, and holds it clear of the slide while the opposite wing propels the slide a proper distance, and then the wing that held out the tumbler lets it in, to fasten the slide and bolts whether the same be in or out.

Then the several parts are finished, as represented, the bolts D D are placed in the case and the slide E and tumbler F placed over them, also the spring G. Then the spindle B and lever C fasten it in, when the latch I-I is placed over the same, and the drops I I are put upon the pins Z el; when the back plate J is put on, and fastened by the screw A', when the lock is complete, l ready for the key K to operate upon it. The several parts D D and E, E, and H I I are made of a proper thickness to fill the space between the case A, and the back plate J, allowing sufficient space for the free action of the same.

I contemplate that ribs may be used upon the bolts instead of slots in them, the ribs to work in projections fitted to them upon the slide, or that the diagonal slots may be in the slide', or ribs upon it, and the pins in the bolts, or notches to fit the ribs.

That I claim as my invention and desire to secure by Letters Patent is- The combination in the same lock, of the bolts provided with two sets of diagonal slots or their equivalents, the slide running at right angles thereto having pins or their equivalents and two key not-ches; and the drops, acting as described, by which I make '.a right and left hand lock, which inust be locked before the key can be withdrawn, and which forces the operator to turn the key in a certain but dierent direction, according as either edge of the lock is uppermost.
